Smelling of "outside".

I've often been told after coming home from walking, running or riding that I smell of the outside or sometimes the cold. Anyone else?
What is it and can it be bottled?
I reckon I could make a couple of quid.

I know this very well, I think it's because when you come in from outdoors you bring an eddy of fresh air behind you loaded with ozone and the smells of grass and trees. Some cold fresh air will also be trapped in your clothing.

Many years ago I realised that rain has a smell; I was doing some, er, bouldering in the Llanberis slate quarries when a storm approached from the summit of Snowdon, across the valley. Suddenly on the wind I smelled rain, quite distinctive and clear. A revelation.

I work for a perfume manufacturer and the holy grails of the industry are the smell of fresh air, the smell of a new car and the smells of baking and freshly-ground coffee. Sadly all are so complex that they can't be reproduced accurately with synthetic raw materials.

Petrichor is the smell of the oils and resins released by your local flora ( in short), so I guess it would vary slightly depending on where you're located. The 'outside', as mentioned above, seems to be known as ozone, but Watermelon Ketone (methylbenzodioxepinone) is a very good synthetic version and has been used in many products for some time - the earthy, musk-like base to something like Brut or Acqua Di Gio or similar perfumes.

Aromas are an excellent thing to get into - amazing how easily a smell can trigger a memory.

That's interesting; I've never heard the word petrichor. The rain I smelled was the fresh ozonic smell of the actual water, not the earthy smell that you get when it hits dry ground.

Watermelon ketone is the popular name for Calone 1951, which is the major ingredient in perfumes like Cool Water and Aqua di Gio as Teasel writes above. Cool Water was a ground-breaking perfume in the way it used hitherto functional raw materials as the main note and it spawned a whole new family of aquatic florals.
